THREE-HORSE EVENER.

SPECIFICATION forming" part of Letters Patent No. 769,661,

dated September 6, 1904.

Original application filed October 12, 1903, Serial No. 176,672. Divided and this application filed February 1, 1904. Serial BIO-191,554.

To It 1071/0711, 7'15 'ntrly concern.-

Be it known that I, SAMUEL A. Masser, a citizen of the United States, residing at Frankfort, in the county of Marshall and State of Kansas, have invented certain new and useful Improvements in Three-Horse Eveners, of which the following is a specification.

This invention relates to three-horse eveners, and is designed more particularly as an improvement on the three-horse evener of which this is a divisional application, filed October 12, 1903, Serial No. 176,672, the special object of the present application being to cover a construction which has the advantage of removing the weight of the tongue off the necks of the horses.

To this end the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 represents a top plan view of a three-horse evener embodying my invention. Fig. 2 is a vertical section taken on the line 11 ll of Fig. 1.

In the said drawings, 1 designates the tongue of a cultivator, wagon, or other vehicle.

2 designates a bolt extending vertically through the tongue at a suitable point, and mounted pivotally upon said bolt at the under side of the tongue and adapted for movement in a horizontal plane is the front evener bar or lever, the same being so disposed with relation to the pivot-bolt that the part 8 shall be about one-half the length of part A. Part 3 is provided with a rearwardly-projecting arm 5 and part at with a similar arm 6, which arms may be formed integral with the bar or lever or may be secured thereto.

At a suitable distance rearward of and in line with the pivot-bolt 2 is a pivot-bolt 7, also extending vertically through the tongue, and mounted pivotally on said belt at the upper side of the tongue is the rear evener bar or lever. Said rear bar or lever is by preference of shorter length than the front one and is also disposed with relation to its bolt '7 so that part 8 shall be about one-half the length a l l l 1 l l l l l l i 1 l l (No model.)

of the other part, 9, the parts 8 and 9 projecting in the same direction as the corresponding parts 3 and A, respectively, of the front evener bar or lever, as shown. At the side of the tongue from which said short parts project is a transversely-extending beam or lever 10, and pivotally connecting the inner end of said beam or lever to the contiguous end of part 8 is a link 11, pitched at an angle to accommodate the different horizontal planes of beam 10 and the rear evener bar or lever, and said beam or lever is pivotally united, as at 12, with the rear end of arm 5. The beam or lever 12 is equipped at its outer end and in the customary manner with the doubletree 13 and swingletrees 1A.

A transversely-extending beam or lever 15 is arranged at the opposite side of the tongue from beam 10 and is of such proportion and so pivoted, as at 16, with relation to arm 6 that its portion extending outward from said arm is about half the length of the portion of beam 10 extending outwardly from arm 5. The portions of the beams inward of the arms to which they are pivoted are of equal length, and the inner end of beam or lever 15 is pivotally connected by the link 17 with the contiguous end of arm 9 of the rear evenerbar, said link being pitched at an angle corresponding to link 11 and for the same reason. The outer end of beam 15 is equipped, as usual, with the swingletree 18.

From the foregoing it will be apparent that the double leverage given the two horses over the one, because the outer portion of beam 10 is twice as long as the corresponding portion of beam 15, is counterbalanced by the front and rear evener bars or levers, the distribution of the pulling strain being as follows: It takes one half of said double leverage to compensate for or equalize the double leverage which the single horse has through the long part of the front evener-bar and the other half of the double leverage obtained through beam 10 to equalize the double leverage which the single horse has through the long part of the rear evener bar or lever. As the machine is drawn forward the beams 10 and 15 apply forward pressure on the front evener bar or lever, and theirlinks 11 and 17 apply rearward pressure on the rear evener bar or lever, this rearward pressure being also applied upwardly, so as to elevate the front end of the tongue and relieve the animals of neck-weight, because beams 10 and 15 occupy a lower plane than the rear evener bar or lever, as shown clearly.

From the above description it will be apparent that I have produced a three-horse evener which possesses the features of advantage enumerated as desirable and which may obviously be modified in minor particulars without departing from the spirit and scope or sacrificing any-of the advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a vehicle-tongue, of a three-horse evener, consisting of a transversely-extending evener-bar pivoted at unequal distances from its end to the tongue; a second transverse evener-bar pivoted at unequal distances from its ends to the tongue but disposed rearward of and in a higher plane than the first-named evener-bar; a transverse beam equipped with a doubletree and accessories at its outer end and disposed at the same side of the tongue as the short parts of said evener-bars, and pivoted to the short part of the front evener-bar and inward of such pivotal point, pivotally linked to the short part of the rear evener-bar; a transverse beam equipped with a swingletree at its outer end and disposed at the opposite side of the tongue from the first-named beam, and pivoted to the long part of the front evener- -bar so that outward of said connection said beam shall be about one-half the length of the corresponding part of the first-named beam; and a link pivoted to the long part of the rear evener-bar and to the inner end of the contiguous beam, the distance between the pivotal point of such link with the beam and the pivotal point of connection of the beam with the front evener-bar, being about equal to the corresponding portion of the other evenerbar.

2. The combination with a vehicle-tongue, of a three-horse evener, consisting'of a transversely-extending evener-bar pivoted at unequal distances from its end to the tongue,

and provided with rearwardly-projecting gletree at its outer end and disposed at the opposite side of the tongue from the firstnamed beam, and pivoted to the arm of the long part of the front evener-bar, so that outward of said connection said beam shall be about one-half the length of the corresponding part of the first-named beam; and a link pivoted to the long part of the rear evenerbar and to the inner end of the contiguous beam, the distance between the pivotal point of said link with the beam, and the pivotal point of connection of the beam with the front evener-bar being about equal to the corresponding portion of the other evener-bar.

In testimony whereof Iafiix my signature in the presence of two witnesses.
